Due to the high water vapor permeability (Sd coefficient approx. 0.05 m) DELTA -EXXTREM can be used for ventilated or non-ventilated roofs. Moisture penetrating from the inside is carried away by DELTA-EXXTREM. The construction of the film allows it to be used on a continuous foundation, such as a shawl, fiberboard, fiberboard, etc. On the outside, DELTA-EXXTREM provides thermal insulation protection against water, snow, dust, etc. The weight of the membrane is 160 g / m and its assembly is particularly easy. Fast unfolding in one plane, without deformation or bulges. Thanks to the increased heat resistance up to 120 ᴼ C and the extended resistance to UV radiation up to the first year, it is ideal for solar and solar panels.

Diffusion-open membrane made of tear-resistant PES fabric with diffusion-open watertight dispersion cover and integrated adhesive zones on both edges.
